LUBRICATOR FOR rrANnsAws.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed February 20, 1912. Serial No. 678,826.

To all whom it may concern Be it known that I, THOMAS RICHARDSON, acitizen of the United States, and a resident of New Orleans, in theparish of Orleans and State of Louisiana, have in vented a new and lmproved Lubricator for Handsaws, of which the following is a full,

container revoluble in the said casing and provided with an openingadapted to regls ter when in one position with the said filling opening,and when in another position with the said outlet.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews. Figure 1 is a perspective view of the lubricator as applied to ahand-saw; Fig. 2 is an enlarged longitudinal central section a of thelubricator with thecontainer in filling position; Fig. 3 is a transversesection of the same on the line 33 of Fig. 2 as applied to a hand-saw;and Fig. 4 is a longitudinal central section of the lubricator wlth thecontainer in discharge position.

The tubular casing A is provided with depending clamping members B, Badapted to engage the opposite faces of 'the saw blade C of a hand-saw Cprovided with the usual handle C against the forward end of which abutthe rear ends of the clamping members B, B, as plainly shown in Fig. 1.The casing A is provided at the bottom intermediate the clamping membersB, B and at the forwardends thereof'with an outlet opening A", and ontop of the casing A directly above the outlet opening A is arranged afilling opening A Within the casing A is fitted a tubular container Dclosed at both ends and having the rear end provided with a rim Dadapted to abut against the rear open end of the casing A, which latteris preferably closed at the forward end, as plainlyindicated in Figs. 1,2 and 4. The container D is adapted to contain oil or other lubricantand is provided with an opening D adapted to register with the fillingopening A at the tune the container D is in the position shown in Fig.2, and the said opening D is adapted to register with the outletopeningA at the time the container D has been given ahalf turn, as shown inFig. 4. The casmg A is provided near the rear end with a vent opening Aadapted to registerwith a like opening D formed near the rear end of thecontainer D, the said vent openings D and A in the posi-- tlon shownunFlg. 4, that is, at the time the open ngD is in register with the'outletopening A. y

' When the several parts are in the position shown 1n Flg. 2, thelubricant is cut ofi from the saw blade C and the container D can beread ly filled with lubricant through the reglstering openings A D Whenit is desired to lubricate the saw blade C the operator gives a halfturn to the container D to move the latter into the position shownjinFig.4, whereby the opening D is moved into register with the opening Ato allow the lubricant to flow from the container D through theregistering openings D and A g being in register with each other i atthe time the container D is onto thesaw blade C and down the forwardedges of the clamping members B, B, the lower ends B of whichare beveledto allow the lubricant to flow down the same and onto the saw blade G,thus distributing the lubri cant on both faces of the saw blade. -Whenthe container D is in discharge posit-ion as shown in Fig. 4, the ventopenings D and A are in register with each other and consequently a freeflow of the lubricant through the registering openings D and A is had,andwhenit is desired to-cut off the flow of oil it is only necessary toturn the container D until the opening D is out of register with theopening A.

The clamping members B, B are preferably provided at the inner faceswith longitudinal recesses B forming a reservoir for retaining the oiland gradually distributing, the same to the saw blade.

The lubricator and oil cup shown and described is very simple andcomposed of few parts, not liable easily to get out of order, and thesaid lubricator can be readily filled with oil or other liquid lubricantand placed in position on the saw blade or removed therefrom whenever itis desired to do so.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A lubricator for hand-saws, comprising a tubular casing closed at oneend and open at the other end, clamping members on the said casing forengagement with the opposite faces of the saw blade to hold the casingon the blade by the frictional contact of the members with said blade,the said clamping members being provided at their inner faces withoil-lubricating recesses extending lengthwise of the clamping members,and a tubular container mounted to turn in the said casing and closed atits ends, one of the ends being outside the open end of the casing topermit of turning the container in the casing, the latter being providedat the top with a filling hole and with a vent hole and at the bottomwith a discharge opening intermediate the said clamping members and atthe forward ends thereof, and the said container being provided with anoutlet port adapted to register with the said discharge opening and withthe said filling hole, and the said container being provided with a venthole adapted to register with the vent hole in the said casing at thetime the outlet port is in register with the said outlet opening.

2. A lubricator for saws, comprising a tubular casing open at one endand closed at the other end and provided on its under side withdownwardly projecting and spaced clamping members for engagement withopposite faces of a saw blade to hold the casing on the blade byfrictional contact of the said members with the said blade, the clampingmembers having recesses on their inner faces for distributing thelubricant on the saw blade, said casing having a fillirig opening and avent opening in its top and a discharge opening in the bottomintermediate of the clamping members, and a tubular container havingclosed ends and mounted to turn in the casing and provided with anopening adapted to register with either the filling or discharge openingof the casing and with a vent opening adapted to register with the ventopening of the said casing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

THOMAS RICHARDSON.
